ADVERTISING DEVICE.v

Application filed July 28,

" sionof lamp boxes designed to be arranged in superimposed relationship, each of which embody separable illuminati-ng units adapted to be connected with companion boxes inorder that any number of boxes may be displayed to advantage and which will obviate the usual necessity of rewiring the boxes when making such change.

lVith the above and other objects in view, the invention further consists of the following novel features and details of construetion, te be hereinafter more fully described, illustrated in the accompanying drawing, and pointed out in the appended claims.

In the drawings: f

Figure 1 is an elevation of a stage or screen illustrating the application of the invention when used in conjunction therewith.

Figure 2 is a longitudinal section taken through an individual lamp box.

Figure 3 is a horizontal section taken through the boxes as disposed in superimposed relation.

Figure 4 is a perspective of a lamp box.

Fi ure 5 is a perspective of a frame member t erefor.

Figure 6 is a similar view of a modified form of lamp box.

Referring to the drawings in detail wherein like characters of reference' denote corresponding parts, the reference characters 10 and 11 indicate the opposed side rails of elongated vertically disposed frame members usually arranged upon the opposite sides of a stage or screen, and which support within the inclosure defined, placards and advertising signs, some of which are illuminated by a shaded lamp carried upon the upper portion of the frame and focused thereon while others embody glass plates, the glare reflected therefrom 1926. Serial No. 125,427.9.

often distracting the attention of a patron by J ocular delusions.

The general characteristic of the invention contemplates the use of lamp boxes 12,`

each of which has provided thereinl a separate lighting or illuminating unit 13. The rear wall of each box has the respective ends thereof forwardly converged to provide refiecting surfaces for the lighting unit, The outer side walls of each box provide channeled portions 14- within which yare received the forward edges of the side rails 10 and 11. Said boxes are disposed in superimposed relation and the lighting units communicated in order that a source of .current supplied to one box will illuminate all of its companion superimposed boxes. The top wall of each box provides an outwardly 'converging edge 15 extending slightly in advance of the channeled portions 15, carried upon the opposed ends of the box. An angularly disposed plate 16 is carried upon the underside of the top and disposed in alignment with the channeled portions 14 the purpose of which will be readily apparent.

,The lower or bottom wall of each box is disposed ina like manner to that of the top walls but in addition provide upstanding flange portions 17.' Frame members, such as indicated at 18 have a length of sign muslin 19 stretched therein. The advertising matter is first sketched thereon while the remaining portion of the muslin is painted to give a desired backgroundA for the advertising matter, and the muslin, in and of itself, when illuminated, will express an opaque or semi-transparent color, free from annoying reflecting propensities. Said frames are slid between the forwardly disposed edges of the top and bottom walls of the box and guidedlbetween the upstanding flange 17. Trunnions or studs 2O are carried upon the opposite ends of the frame members and adapted for engagement with fastening elements 21 carried upon the outer sides of the channeled portions 14 whereby said frames will be held against displacement from the lamp boxes.

In Figure 6 of the drawings, I have illustrated a modified form of lamp box which is devoid of the channeled portions 14, and forwardly projecting edges 15, as in the instance of preferred form of the invention. The forward edge of the bottom wall of the modified form of lamp box provides an upwardly extending flange portion 17', the edge thereof being disposed in direct alignment with the edge of the top wall. A flange portion 16 is arranged upon the inner sides of the top wall and ends of the box and in slight spaced relation to the corresponding edges thereof. In this form of the invention it is no longer necessary to employ the side rails or any other portion of supporting structure other than that which is carried by the box itself. This is accomplished by plate members 22 carried upon the ends and outer sides of each box, and which terminate at their inner ends in inwardly extending offset portions 23 which are disposed in the same horizontal plane with that of the intermediate portion in the length of the lamp box and which are adapted to lie flush against awall upon which the lamp boxes are secured by fastening' elements, not shown, inserted within openings 2a drilled within the said intermediate portion. The forward edges of the sides and plates 22 provide registering bayonet slots 25 disposed ofi' center thereof and which are adapted to receive therein the pins or trunnions 2O carried upon the opposed sides of the frames 18, the lower rails of which are dropped behind the upstanding flange portion 15 while the inner marginal edges thereof abut the flange 16.

In either instance, whether the preferred or modified form of the invention is employed for illuminating purposes the result is the same in the illumination of a particular frame. Many colorful effects may be attained and the advertising matter displayed to advantage but may not refract, intensify nor magnify the light from a lamp box in so far as the light exposed through the .advertising matter will be subdued or opaque.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is hereinr reserved to make such changes as properly fall within the scope of the appended claims.

Having thus described my invention, what is claimed is:

1. An advertising device comprising an illuminated lamp box, a frame member, channeled portions provided upon the ends of the box for receiving the edges of the frame member therein, the forward edges of the top and bottom walls of the box protruding outwardly an appreciable distance beyond said channeled portions, the lower wall providing an upstanding iiange portion, and a frame member carrying a placard thereon being disposed between the walls behind said liange portion.

:2. An advertising device comprising a lamp box, the top and bottom walls thereof protruding an appreciable distance forwardly and beyond the side edges thereof, an elongated franie, channeled portions provided upon the opposed sides of th-e box and carried by the elongated frame, a flange portion carried upon the inner side of the box, an upstanding {iange portion provided upon the forwardly extending edge of the lower wall, and a frame member positioned between said flange portions for closing the open end of the lamp box.

In testimony whereof I affix my signature.

HERBERT S. SACKETT.
